It takes time to develop relationships that lead to sales, but a large percentage of marketers who take the time find great results. For example, 58 percent of marketers who have been using social media for more than three years report it has helped them improve sales. More than half who spend 11 or more hours per week find the same results, and over 65 percent of those who spend 30+ hours earn new business through their efforts.
Small business owners with two or more employees were more likely to see improved sales from social media (51.5 percent). Conversely, 60 percent of all marketers completing the Social Media Examiner survey report social media has not helped them improve sales. This may be because they lack tools to track sales.
